Has anyone used one of these or know anything about them? and before Julian says anything i know they are a heater and cartridge shaped,i have a cunning plan for one

Looks like a great find and cheap too.
Only thing I've played with that's similar is a couple of soldering iron elements which I've started cobbling together as a mini hot pan tester. Yet another unfinished project and now superseded buy a £16 solder pot off ebay which needs modifying ... for which I need some assistance with the electronics.
C'mon, spill the beans, what punning clan do you have in mind?

Well,i was thinking of an "L" shaped pipe,the bottom of the L been copper,90 comp fitting then plastic pipe,the cartridge would go in the copper bottom bit,cable coming up and out the plastic,then the bottom of the L would fit through a cubie lid hole/or in tubs for melting solids,if it gets too hot then i would solder some small legs onto the copper pipe to keep it off the bottom,unless there is something obvious ive missed i thought it would be worth a try for £3 and some scrap bits
Waddya think?
Thought this was interesting as well,but a bit expensive

Nice find Keith! (The 220V one)
I wonder if the wires are oil/bio resistant? All the ones I've tried (admittedly designed as water heaters) had the cabling fail.
Would a pipe fitting actually seal on the body of that tube or do you think it would just crush?
Could be a side-fit element in a settle tank (bio or oil) or possibly a glyc warmer (keep that NaOH glyc liquid between two-stage)?
-
Keith you're a bad influence - I've bought two!
-
Sounds ok to me. Tony did some experiments resting a heater on the side of an oil filled cubie (heater in the oil obviously) and it never melted the plastic.
Just typed the following and went to post only to find Tony beat me to it! ...
You can get 10mm compression fittings which you might fit the heater directly, especially if they have copper olives. That way you'll get far better heat transfer and no convection losses up the 'L' shaped pipe work.
-
Well its arrived,nice little thing if it works.
I have fitted the cartridge into a 10mm reducer in a 15mm straight connector,then a piece of 15mm copper pipe bent to 90,then onto 15mm plastic.
The power lead goes up the inside of the pipe and is water tight,i will give it a test in oil tomorrow and hopefully i will get a tub of solid tomorrow as well.
The first thing i want to check is if the heater will melt a cubie/tub if it does i will attach a piece to keep it away from the surfaces,about £7 spent so far
-
Looking through the suppliers other items i spotted this,might have its uses somewhere

Given previous experiments with a 500W element against the sides of a cubie (submerged) I don't think you've got much to worry about with this one.
So it is 10mm bore and you've fitted a 10mm compressionfitting to it OK?
-
9.3 but a copper olive and a big spanner sorted it
-
0.7mm, that's nothing vs a big spanner :)
-
So do you think that it could be used as an inline heater? Creates some interesting drying/spraying possibilities. Though the lack of thermostatic control might be an issue.
-
Its not quick but it certainly does the job,i need to get a tub of solids and time the melt,must be a lot of uses esp the larger sizes,has it got a use in your flasher evaporater?

Not for a flash evap, not enough power :)
I also wonder if you could seal it in a tube entirely with mineral oil like an electric oil radiator, to increase the surface area?
Liking the work above - all the cabling safely away from the oil, I do like that!
-
Nice simple idea, well done.
Often with heating elements, the section near the connections stays much cooler than the business end. If this is the case with these, what do you recon to one of these controllers (RM had a 240v version) with the probe just stuck inside the copper pipe near the bottom compression fitting.
Mount a little box on the plastic pipe using a tank connector to house the controller, gland for the cable ... should work OK.
-
Ive got one of those boxes,it was the wrong colour display! for RM so he gave it to me
Got my tub of solids,but the whole plan is scuppered! SHMBO has spotted it and said no way is it going in the fridge!,any idea how cold it needs to be to solidify again?
-
Why not pop down the chippy and grab a tub of palm? Around here they can't get rid of the stuff.
-
Does she know how many people she's upsetting? There's a whole internet out there waiting for news of it's performance.
Immersing it in running tap water should get it down to about 10°C.
-
She says until she has seen written permission from both your wives she will not let me put my tub of prep in our fridge,until then i am awaiting a cold snap-bugger!
Mind you if i stick it in the fridge anyway it will probably get frosty around here
-
Threaten to withdraw conjugal bio until she sees sense.
PS ... I get away with putting all my sample jars, 3/27 kit and oily jugs in the dish washer. Haven't yet trained her to deliver the washed items to the shed ... but I'm working on it.
-
Got a small chest freezer sat in the garage now,so i should be able to test it tomorrow night
-
My hot sticks turned up today, smaller than they looked in the eBay photo aren't they? :)
I also sneak glasswear into the dishwasher, don't tell the missus shh

With one of those controllers I mentioned above and a relay, you can do climatic testing and cold filtering of winter fuel.
Just out of principal, don't let her put any food in it.
-
Climatic testing?,i like the sound of that,whats involved?

What I did testing for HMPEs.
Sorry, I think I might be infected with "suit speak"! I've been asked to do some work for a rather techie company. They don't have problems, they have challenges and instead of teaching people stuff, I've been asked to get involved with "skills transfer".
The other day the word "native" was used in connection with a bespoke component. When I queried why the chap was using the term he admitted he had made it up!
Being the sarcastic old sod that I am, I think some fun could be had by inventing my own terms to use back at them.

Don't forget the piccy's when you have a group bonding session
-
Think you mean team building.
-
Group bonding sounds a little too near the mark for me.
-
Success!
I successfully melted the side of the prep tub and successfully oiled my garage floor!,now who was it a few posts earlier that thought it would be OK?
Anyway ive added a bit which keeps it away from the sides and as it sits back on the bend its now fine
(http://i316.photobucket.com/albums/mm323/KRH01/f717e99b.jpg)
It takes about 60 seconds to melt through the surface but all my other timings will have to wait until i refreeze it,mopping up got in the way,i wonder how quick it needs to be?,obviously a bigger heater would be faster,i guess people could buy whatever size they want (ive got a 14mm 600w one coming)

Gulp!
Maybe my 500W element, being longer, didn't get so hot in one spot as those tiny little elements!
Sorry about the floor and cleanup Keith.
-
Got another element today,600w 14mm,big spanner time again
One for Julian - someone said it should be called a s**t stick!

At least tosser towers is fully built ;D

We tried these last year as an inline heater by soldering one into a 22mm T fitting and keeping the flow running throught the other two connections.
It worked well until the heater melted the solder and the flow of oil pushed it out of the fitting!! It would probably work fine using compression fittings though.
Is there a reason that you're not buying the 15mm ones that wouldn't need a big spanner?

-
Oooh nice find... might have to pick up one of them :)
-
The reason for using the slightly smaller version is a bit complicated and to do with optics,
RM might have a go at using the smaller one in the block heater i made or make another version of it
-
Anyone done anything with there cartridge heaters?

all the good stuff seems in hong kong ::)

Well actually mine are being subverted from the intended bio lark to go in my friend's beer brewing kit as an inline heater for the mash stage.
I'm sure I'll get to enjoy the results :)
